Question 200

At Riverton Utilities, the infrastructure database operations team maintains a private metering and regulatory reporting system with requirements for change control and loss-bounded recovery. After a claimed fix, the release reviewer evaluates: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Which observed result BEST proves the intended problem is corrected?

  1. A test connection negotiates the required TLS channel and a deliberately noncompliant client connection is denied.
  2. The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.
  3. DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing.
  4. An approved private client connects using the intended private address and an unapproved external connection fails.

Explanation

Correct Answer

D:

An approved private client connects using the intended private address and an unapproved external connection fails. That observable result supports resolution of: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. The corresponding corrective change is: Configure a private endpoint and private DNS with appropriate network rules and disable unnecessary public network access. The Riverton Utilities reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

A test connection negotiates the required TLS channel and a deliberately noncompliant client connection is denied. That result is evidence for another corrective change: Require supported encrypted SQL connections and validate server certificates and client driver encryption settings. The alternative problem is: An application attempts to connect to Azure SQL by unencrypted TDS because it assumes VPN transport replaces all database-layer TLS requirements. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.

B:

The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy. That result is evidence for another corrective change: Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing. The alternative problem is: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.

C:

DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing. That result is evidence for another corrective change: Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname. The alternative problem is: A network migration replaces a database's public hostname with a private endpoint but client DNS still resolves the old public address. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.

Question 201

At Riverton Utilities, the infrastructure database operations team maintains a private metering and regulatory reporting system with requirements for change control and loss-bounded recovery. A routine platform check identifies: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. Which action BEST resolves this specific database administration problem?

  1. Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname.
  2. Distinguish service endpoints from Private Link and select private endpoints when private-address access and public exposure reduction are required.
  3. Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing.
  4. Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption.

Explanation

Correct Answer

C:

Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing. This addresses the specific Azure SQL or SQL Server operational issue: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. The Riverton Utilities team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

Incorrect Answers

A:

Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname. That relates to a separate SQL administration problem: A network migration replaces a database's public hostname with a private endpoint but client DNS still resolves the old public address. The Riverton Utilities requirement is instead: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. That approach does not directly establish the required fix; the requested acceptance evidence is: The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

B:

Distinguish service endpoints from Private Link and select private endpoints when private-address access and public exposure reduction are required. That relates to a separate SQL administration problem: A security team assumes a service endpoint automatically gives a database a private IP address inside the application's subnet. The Riverton Utilities requirement is instead: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. That approach does not directly establish the required fix; the requested acceptance evidence is: The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

D:

Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption. That relates to a separate SQL administration problem: A team wants an administrator who can run queries to be unable to see highly sensitive column values, but proposes only transparent data encryption. The Riverton Utilities requirement is instead: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. That approach does not directly establish the required fix; the requested acceptance evidence is: The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

Question 202

At Riverton Utilities, the infrastructure database operations team maintains a private metering and regulatory reporting system with requirements for change control and loss-bounded recovery. The operations owner asks for a validation result for: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. Which observed result BEST proves the intended problem is corrected?

  1. A client resolves the expected private endpoint DNS chain and reaches the service over the permitted private route.
  2. DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing.
  3. A test connection negotiates the required TLS channel and a deliberately noncompliant client connection is denied.
  4. The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

Question 203

At Granite SaaS, the tenant database platform team maintains a multi-tenant business application backed by Azure SQL with requirements for tenant isolation and consistent provisioning. The database operations review identifies: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. Which action BEST resolves this specific database administration problem?

  1. Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing.
  2. Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption.
  3. Configure transparent data encryption with an eligible customer-managed key in Azure Key Vault or managed HSM according to the service rules.
  4. Distinguish service endpoints from Private Link and select private endpoints when private-address access and public exposure reduction are required.

Explanation

C:

Configure transparent data encryption with an eligible customer-managed key in Azure Key Vault or managed HSM according to the service rules. That relates to a separate SQL administration problem: A regulated Azure SQL Database uses default platform-managed encryption keys but requires customer-controlled key rotation and revocation evidence. The Granite SaaS requirement is instead: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. That approach does not directly establish the required fix; the requested acceptance evidence is: The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.

That result is evidence for another corrective change: Evaluate Always Encrypted with secure enclaves and the required hardware, driver and database feature support for the intended computations. The alternative problem is: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. The current Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

B:

The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy. That result is evidence for another corrective change: Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing. The alternative problem is: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. The current Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

D:

An authorized application decrypts a test value while a database administrator query sees ciphertext rather than plaintext. That result is evidence for another corrective change: Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption. The alternative problem is: A team wants an administrator who can run queries to be unable to see highly sensitive column values, but proposes only transparent data encryption. The current Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.
